How is your hot water flowing?
I got an emergency water heater replacement call today; it’s an emergency for the residents who do not have hot water! Whenever we work on water heaters, we check for other potential problems because this would be the time to correct the problem. With the water to the unit shut off already, a couple of changes will cost next to nothing in additional labor. We always change the flex lines, check the straps, secure exhaust vent, and test pressure relief valve.
At the shut off valve there was a short galvanized pipe that was loaded with rust inside the pipe. The photo below shows that even a galvanized pipe can rust. The entire water system is made of copper, except for this short 3/4” pipe, but if it were to continue to rust the water flow would be restricted. The opening will begin to close up and the water will be passing through a much smaller area, it may even completely close – no hot water.
